DEVICE FOR HEATING FEED-WATER.

Specification of Letters Patent.

Patented Nov. 22, 1910.

To all whom it may concern:

Be it known that I, JOHN FOURNIA, a citizen of the United States,residing at the city of Albany, in the county of Albany, and Stateof-New York, have invented certain new and useful Improvements inDevices for Heating the Feed-VVater of Boilers, of which the followingis a specification.

My invention relates to devices for heating the feed water of boilers,and the object of my invention is to provide an efficient and economicalmanner for applying heat to the water supply of a steam boiler,particularly adapted for use in locomotives. I accomplish this object bymeans of the mechanism illustrated in the accompanying drawings, inwhich:

Figure 1 is a side elevation of a locomotive and tender supplied with myinvention. Fig. 2 is a perspective view of the pipe through which thewater circulates.

Similar letters refer to similar parts throughout the several views.

I arrange a coil of pipe, A, in such a manner that there shall be aseries of rows of pipe separated from each other, with a space betweenadjacent pipes of each series, provided for the circulation and flow ofsteam between and about each of the pipes forniing the coils coming incontact with the entire surface thereof. I place a coil of pipe thusarranged within a box, B, preferably on thetender, as shown in Fig. 1and connect the same by means of a pipe, C, with a pump, D. The otherend of the coil is connected. by means of the pipe, E, with the boiler.The box, B, is covered and closed tightly, making a steam containingreceptacle, which is connected by means of the pipe, F, with the pistonvalve steam chest, K, and the exhaust of the engine. Whereby the exhauststeam from the engine is carried through the pipe, F, to the box, B. Bythis arrangement of the pipes, A, within a steam containing receptacle,B, the feed water in its passage through the coil will become heated andforced into the boiler under the pressure of the pump. Because the wateris compelled to travel throughout the coil and thus brought in contactwith the surface of the pipe heated by the steam before it is deliveredto the boiler it becomes much warmer than if it were pumped into areceptacle through which steam pipes were used for heating the contentssince the continuous flow of the water in the pipes necessarily keeps itin closer contact with the heating element than if it were simply forcedin an apartment heated by steam passing through lpes.

What I claim as my invention and desire to secure by Letters Patent is:

The combination with a locomotive and its tender of means for heatingthe feed water for a locomotive; comprising a box located on the tender;a coil of pipe arranged in such a manner that there shall be a series ofrows of pipe separated from each other, with a space between adjacentpipes of each series, whereby the steam supplied to the box willcirculate between and about each of the pipes forming the coil, comingin contact with the entire surface thereof: a means for conveying waterto be heated to said coil; a means for connecting said coil with theboiler of the locomotive; a means for conveying steam to the interior ofsaid box.

In testimony whereof I have affixed my signature in presence of twowitnesses.

JOHN FOURNIA.
